Abstract :
The material properties, focusing on the properties used for design analysis were re-assessed and newly investigated for various heats of reduced activation ferritic/martensitic steel, F82H. Moreover, irradiation effects on those properties were studied in this work. Most of physical properties of unirradiated F82H are insensitive to the heat-to-heat variation, and more preferable to Grade 91 specified in the ASME code. Therefore numerical analysis using data of Grade 91 can be a conservative evaluation for F82H. The change in these properties of F82H is less than 6%. Therefore the irradiation effects on thermal stress and variation of electromagnetic force in plasma disruption could be quite small in the irradiation conditions studied.
